Introduction Features
1.2 Features
System board
The features of the system board (D2300) are described in the technical manual
for the system board in relation to the hardware and in the BIOS setup manual
(see “Literature” on page 89).
Hard disk drives
The server can accommodate two 3.5 inch or four 2.5 inch SAS/SATA hard disk
drive modules. Each hard disk drive module (HDD module) can accommodate
a SAS/SATA hard disk drive with a maximum height of 1 or 0.5 inch. The module
is connected to the SAS/SATA backplane without cables. This allows hard disk
drive modules to be simply plugged in or pulled out (for further details see
section “Hot-pluggable hard disk drives” on page 69).
The internal hard disk drives are controlled exclusively by the onboard SAS
controller.
If the server has a RAID configuration, the HDD modules can be exchanged
during operation (hot plugging).
Onboard SAS controller with IME functionality
The SAS controller is equipped with "Integrated Mirroring Enhanced" function-
ality for operating internal hard disks. "Integrated Mirroring Enhanced" also
provides RAID 0.1 functionality for configuring the internal hard disks
(IME Level 1).
I To configure "Integrated Mirroring Enhanced", the controller has its own
RAIDSelect Utility. For further information, refer to the “Integrated
Mirroring User’s Guide” on the ServerBooks CD (select “Controllers” from
the menu).
Zero Channel RAID (ZCR) controller (option)
Optionally a ZCR controller (PCI card) can be installed. In addition to RAID
levels 0 and 1, this RAID controller also offers the option of configuring RAID 5.
The ZCR controller uses the Onboard SAS controller using logic that is specially
integrated on the system board.
